an Implementation Project File </title><abstract>An implementation project file is a .mmp file, which specifies the

essential elements of the implementation. The project files are used for project

development. The implementation project file contains information (source

file, build file) about the implementation that is being built.<shortdesc>The

format of implementation project file is dependent on the version of the Symbian

platform used. The differences basically reflect the introduction of platform

security into Symbian OS v9.0 and later versions. </shortdesc></abstract><prolog><metadata><keywords/></metadata></prolog><taskbody>

<info>Set <codeph>RESOURCE</codeph> to the registration resource file of the

implementation. </info>

<info>From v9.1, the name of the registration resource file must be the same

as that of the executable. </info>

<info>For example, if the plug-in is <filepath>foo.dll</filepath>, then its

registration resource file must be called <filepath>foo.rsc</filepath>. This

is because plug-in framework uses the names of the registration resource file

to find the plug-in DLLs. </info>

<info>A simple <codeph>START RESOURCE</codeph> statement is of the following

form: </info>

<stepxmp><codeblock id="GUID-B4DAAEEF-0FDA-5192-81F5-650946430C2E" xml:space="preserve">START RESOURCE foo.rss

END</codeblock> </stepxmp>

<info>This builds a file named <filepath>foo.rsc</filepath>. Registration

resource files are always built into the target directory <filepath>\Resource\Plugins</filepath>.

There is no need to explicitly set the target directory for the <filepath>.rsc</filepath> file

in the project file, the build tools take care of it. </info>

<info>Where the registration resource source file is still named after the

UID of the DLL, the built resource file can be renamed to be the same as the

DLL, using the <codeph>TARGET</codeph> keyword. For example: </info>

<stepxmp><codeblock id="GUID-E2636CC2-9658-57CD-B57E-FF244CFE6A59" xml:space="preserve">START RESOURCE 10009DB0.rss
